intl

Cauchy integral

Calling Sequence

[y]=intl(a,b,z0,r,f)

Arguments

z0

a complex number

a, b

two real numbers

r

positive real number

f

"external" function

Description

If f is a complex-valued function,
intl(a,b,z0,r,f) computes the integral of
f(z)dz along the curve in the complex plane defined by
z0 + r.*exp(%i*t) for a<=t<=b
.(part of the circle with center z0 and radius
r with phase between a and
b).
